Can you take melatonin and Concerta?

My psychiatrist says "NO"... he just took me off of Lyrica. He said that he recently read a study which reported that taking a combination of Concerta and Lyrica causes a very significant amount of memory loss. Believe me: he is absolutely correct!

--Whatever I did each morning, I would think in the afternoon that I had actually done that yesterday!

--Every morning, I would have to look at my PC clock in order to see what date and day it was.

--I would go to get something in another room and when I got there I couldn't remember what the reason was as to me being in that room.

--I went through a RED traffic light. My wife was constantly telling me things I had done, said, or already heard the past several days.

--I was constantly: rewinding movies; reading a paragraph in a book over and over again... etc.
